Dear Users,

I have released version 5.73 of stunnel.

### Version 5.73, 2024.09.09, urgency: MEDIUM * Security bugfixes   - OpenSSL DLLs updated to version 3.3.2.   - OpenSSL FIPS Provider updated to version 3.0.9. * Bugfixes   - Fixed a memory leak while reloading stunnel.conf     sections with "client=yes" and "delay=no".   - Fixed TIMEOUTocsp with values greater than 4.   - Fix the IPv6 test on a non-IPv6 machine. * Features   - HELO replaced with EHLO in the post-STARTTLS SMTP     protocol negotiation (thx to Peter Pentchev).   - OCSP stapling fetches moved away from server threads.   - Improved client-side session resumption.   - Added support for the mimalloc allocator.   - Check for protocolHost moved to configuration file     processing for the client-side CONNECT protocol.   - Clarified some confusing OpenSSL's certificate     verification error messages.   - stunnel.nsi updated for Debian 13 and Fedora.   - Improved NetBSD compatibility.
